How to Write a Translation Style Guide

Quick answer — A useful translation style guide is a list of decisions, not adjectives. Formality, numbers, dates, units and punctuation settled per language, with before-and-after examples — two pages that get followed beat twenty that do not.

Why most style guides do nothing

They describe a feeling. Warm but authoritative. Clear and concise. Professional yet human.

None of that survives contact with a sentence. Two translators reading the same adjective produce different text, both defensible, and the guide has settled nothing.

A style guide earns its place by removing decisions, not by describing a mood.

Settle these, per language

Formality is the one that cannot be skipped. German and Japanese make a grammatical formality choice English does not, so leaving it unstated means the first translator decides it and the second decides differently.

Examples do the work

For each rule, one sentence done wrong and the same sentence done right.

Three pairs per language teaches more than a page of prose, because it shows the rule operating rather than asserting it. It also gives reviewers something to point at, which turns a disagreement about taste into a comparison against a written decision. Keep the whole thing to two pages. A guide nobody finishes reading is a guide nobody applies, and length is the most common reason it goes unread.

Keep it separate from terminology

The style guide governs how things are said. The glossary governs what things are called, and a term with consequences belongs there where it can be pinned.

Mixing them produces a long document that is advisory in both directions.

Tone and terminology are both applied at translation time rather than checked afterwards, so the first output already follows the guide — which is the same argument made in brand voice, and what lets quality control verify against something written down rather than against an opinion.

Corrections then write back to memory. Safety wording is the case where the guide has to override natural writing — electronics safety warning translation.

FAQ

What makes a translation style guide useful? Decisions rather than adjectives. Formality, contractions, numbers, dates, units and punctuation settled explicitly per language, each verifiable, with before-and-after examples showing the rule in operation.

How long should a translation style guide be? About two pages. Length is the most common reason a guide goes unread, and an unread guide changes nothing. Three worked examples per language teach more than several pages of description.

What is the difference between a style guide and a glossary? The style guide governs how things are said; the glossary governs what things are called. Terms with consequences belong in the glossary where they can be pinned and cannot be overridden.

Which style decision is most often left unmade? Formality. German and Japanese encode a formality choice that English does not make, so if the guide is silent the first translator picks one and the next picks another.
